RESEARCH THE STRESS-DEFORMED STATE OF CIRCULAR PLATE BY NON-CLASSICAL THEORY USING FINITE DIFFERENCE METHOD

Abstract

This paper presents the application of the finite difference method to study the stress-deformed state of the circular plate according to the non-classical theory. The stress-deformed state calculation model for a circular plate was built based on the basis of a 3-dimensional coordinate system, which is a system of second-order differential equations with variable coefficients. To solve this problem, it is possible to use approximation methods, and numerical methods such as the finite element method, and finite difference. In this paper, the author presents the application of the finite difference method to solve the problem of the circular plate subjected to local loads. Based on the calculation results, a comparison of the results obtained by classical and non-classical theory has been made.
